Coating machine is mainly used for surface coating process production of film, paper and others, such a machine is to coat the rolled material with a layer of specific functions of glue, paint or ink, and then dry and wind it. In the whole process, slip ring, being an electrical connector in 360° rotation, is an essential part for achieving its operation.
JINPAT has accumulated much experience in the slip ring development for coating machine. The recent coating machine slip ring is a through bore part that supports electricity and K thermocouple signal transmission. Working in a high temperature up to 150℃, the K thermocouple wires are in a special processing to avoid an excessive heat. Moreover, power ring is also designed with decreasing heat dissipation. Continuous rotation of the through bore slip rings promotes a non-stop operation with roll alternation.
